out the liability of an explosion occurring such as Wouldf'takev place in -case the damper or door 18fw'as opened for thispurpose.-

The fuel conduit 12 communicates with the upwardly. extending` flues 21 which communicate with the openings 22'in'the 'interL locking iiu'e' tiles '23 which form the bottom ot' the'annealing chamber 24. The openings.

SFdesignates corner tiles, `vvhich interlock with theadjacent tiles 25 and iwith the arch tiles 28, the construction of-Which corresponds to thetiles 25. The'arch` tiles are spaced from eachother by. means'ofthe interlocking tiles 29,` the construction offwhich correspondsto the the interlocking tiles 26 and 29 is to not onl space .the diierenttiles from` each other-, ut also to prevent the falling of' a Vtile in case it should become broken.V The tiles 25,' 27 and 28 form aV flue 30',- which communicates andiviththe ports 31 Which open into the 32, one Wall of which' is formed by the inter ocking tiles L 3, which are provided with a tongue on one sid and a groove on the opposite side in order to accomplish this result. These Wall tiles'33 are recessed, as at 34, in order to reduce-th thickness of the tile at such point,

so that-the heat will more readily-radiate on the-opposite sides with the hemispherical` recesses35', thereby 'adapting the same to interlock'with the ends of the regenerative or recuperative tiles 36, which latter extend transversely across the` air conduit 37. The opposite wall of said conduitS-ljis formed by interlocking tiles 33 which also formA a wall of adischarge conduit 38, the other side wall of said discharge conduit being formed by the tiles 39. The ydischarge conduit 38 The side Wallof the leer isprovided with the apertured tiles 41 vWhich communicate with the cornerfti'les 2i" and form cleaningopeninxrs,

through 'which a suitable implement may be' inserted to clean vthe arch tiles.' and these tiles41 are'sealed by means of a closure 42 4 3' designates v the arch of the furnace which forms the top Walls of the annealing-4 chamber24.

tween the vertical fines, and said tiles 44 are sealed by. means of removable closures 45.

The-fines which communicate Vwith the tuel conduit 13 are formed in a similar manner to those which com i' nicate With the iucl conduit 12, and adeltail description thereof is therefore believed .to be' unnecessary. '.lhe fuel conduit 13 communicates with vertically extending ilues 46, which, in turn, communicate with arch fines 47. The latter lues communicate With downwardly` extending at itsxrear end, as at 57, into afconduit* which communicates by meansiofthe pas-4 sages 59 with the vertically extending'llues 2.1 as Will be bestunderstood by reference to Figuresy 1 and 3.

60 designates an air inlet controllediby a door or damper 61, whereby the admission of air to the conduit- 37 may be regulatedv as desired, the air in said conduit passing around the tiles 36, then to the downwardly extendingpassage'l through the longitudinally extending conduit 64, which communicatesby. means of the laterally extending passage with the fuel passing through the conduit 46'.

The bottom of the annealing; chamber 24 is'provided with spaced bars 66,1provided in their upper lface with recesses G which form bearings for the'S journals 68 ot" the rollers 69. The purpose oflthis construction is to prevent the rollers or anti-friction devices 69 becomingfi'xed and inoperative,l due to the presenceof foreign material, and ow ing to the provision ot' the recesscs`67, a sut'- icient amount of play is provided' which prevents any foreign materialv from filling up the space in proximity to said rollers soy that their rotation is prevented. Thesebars extend from' Ain proximity tothe openingA 70 to the discharge end 7l ofthe annealing' chamber. The'top.of'th'e discharge passage 7'1 is f'rerfe'rably orme'dby aseries of arches 72. Lhe ,trays orpans on which the articles to be annealedr are placed are inserted through' the' opening 70, which latter in ay be closed by means rof 'a door 73.4 The pans roll The fuel conduits 12 and 13v maybe provide-.l with openings 74 and 75, respectively, (see 'Figure 3) which, it will be understood' are close-d' in case producer gas is employed. and these openings are employed-'for the insertion oi a burner, such as for example,a fuel oil mecs burner, in case 1t 1s desired to lire the leer in such manner. i

1I?.k the operation, the tuel passes from the main fuel conduit t through the branch con* i 60,' so that prior toits intermin'gl'ing with theproducts of combustion, it is highly heatedb 'the waste products of combustion. T e products of 'combustion pass through the different lines in such a manner that the direction of t-heanie'in one tlue is in 'a direction'reverse tcftgat inthe next adjactnit Hue, so that the annualingl chatnber isy uniformly heated throughout the length thereof. The heat radiates from the fines intothe alngxealing chamber so that the articles to be annealed do not come into con tact with. the darne, and l am therefore enabled to employ a temperature Yin the a nealinp,y chamber which highef than that `which would melt the articles to de annealed in case the flame came into diret Contact therewith. Q'Ihe air for combustion is very highly heated, since the tiles 5l and 36 in practice'beconie red hot. ln case the products of combustion are permitted to come into direct Contact 'with `the tclass beingf annealed, the product is often discolored and .the quality of the ware affected, owing to the absorption by the glass or'J4 foreign ini-l purities,'carried by the products of combustion, such as for example, sulfur, soot,- and other foreign material. n

It has been deemed nnpractlcal `1n the ,inethods heretofore employed. to .use pro- .,ducer gas -for firing leers/ owing to the conlarge amount voit foreign impurities tained in the sa and since producer gas costs about, that of other types of fuel, the cost of the annealing operation in 'my present leer is reduced to about halt' the cost of that which incurred in prior methods. In my present invention, the annealing* furnace can he continuously `operated and it .is not necessary' to shut down the operation at any time.

In case soot and foreignrinaterials collects in the different flue-s, the ,eas may be ignited 'l through they port 19 and the sootnd the nfnlnnerof forming the different fides whic foreign material burnt out. A

Special attention is drrectedkto the novel are interlocled both longitudinally and erally of such lines. so that they are not liable to hec-orne displaced. l provide nieans for inspecting the state of combusftion in -eac-h ilue owing to the fonizrollfible opening colnmunicati with the corner tiles of the flue, as seen in Future and these `'openings may also be used 'for cleaning the flucs.

if desired. The closures for" such openings and thc ports also serre as explosion ports and ports through which fluid under 'pressure may be introducedbetween the lines.

lt will new be apparent that l have devised a novel and. useful construction of a leer 'which embodies the -features of advan.- tage enumerated as desirable in the statement of the invention and the above description., and While I4 have, in the present instance, shown and described a preferred `elnhodiinent thereof which Will give in practice satisfactory and reliable results, it is lto be understood that the saine is susceptible of` modilication inV various particulars Without departing from the spirit or scope of the invention or sacrificing any of its. advantages;
